- specification.

My invention relates to machines for cmbossing paper, wood, and othersimilar materials; and it consists in certain novel features ofconstruction, arrangement, and combination of parts, which will bereadily understood by reference to the description of the drawings, andto the claims to be hereinafter given.

Figure 1 of the drawings is a side elevation of so much of a machine asis necessary to illustrate my invention. Fig. 2 is a central verticalsection of the same, the cutting-plane being parallel to the side of themachine.l Fig. 3 is an elevation of the side of the machine opposite tothat shown in Fig. 1. Fig. 4 is a front elevation of the upper portionof the same with the feed apron and roll removed, and Fig. 5 is asection ofa portion of the feedapron. Y

In the drawings, A A are the side frames of the machine, connectedtogether by the tierods B B, and having bolted to their upper edges thestands A A', slotted to receive the boXes O C, in which is mounted theengraved embossing or die roll D. The upper ends of the stands AA aretied together by the cross- 'head E, provided with the long slot a, inwhich is fitted the wheel-nut F, which works upon the screw b, firmlysecured in the tie-bar G, connecting the boxes C C in such a manner thatby turning the wheel F the boxes C C and the embossing-roll D will bemoved upward or downward, according to the direction said Wheel isturned. The lower ends of the stands A A' are firmly bolted to thebed-girt I-I, provided upon` its upper side with a rounded rib, c, theapex of which is directly beneath the axis of the embossing-roll D, asshown.

I is the feed-apron, mounted upon the rolls I and I2, and composed of alayer or thickness of leather, d, and a layer or, thickness of rubber,c, the two materials being firmly secured together over their entirecontact-surfaces by means of rubbercement or other suitable adhesivematerial, so that the rubber, while it may yield to the pressure of theembossingroll, cannot stretch longitudinally or laterally. 'y

This belt or apron passes between the embossing-roll D and t-he bed-girtI:I, and upon its surface rests the sheet or web of paper or othermaterial to be embossed as it is being fed through the machine.

The shaft of the embossing dierol1 D has mounted upon one end thereofthe spur gearwheel J, with the teeth of which the teeth of the pinion Jengage to impart to said roll a rotary motion. The pinion J is mountedupon one end'of the shaft K, mounted in bearings in the arms L, securedto or formed in one piece with the boxes C C, and carrying at its otherend the driving-pulley M. The shaft of the die-rollD also has mountedthereon the gear-wheel N, which, acting through suitable intermediategears, N and N2, and the gear N3, secured upon the shaft of the roll 12,imparts to said roll IZ a rotary motion, and causes the apron I to bemoved around said rollat a speed corresponding to the speed of theperiphery of the die-roll D.

O is an endless metallic apron mounted upon the roll O' and another (notshown) at any suitable distance from O', said apron being moved inunison with the apron'I by means of the gearwheel O2, mounted upon theroll O,'and the intermediate gear-wheel meshing into said gear-wheel O'land the gear N3, as shown. The apron O is heated by means of a coil ofpipe, P, interposed beneath the upg per portion of said apron, intowhich steam is admitted through pipe P', connected with any suitablesource of supply, and from which it is discharged at the opposite end ofsaid coil.

It is designed to make the apron O of sufficient length and extend thecoil of steam-pipe to sufficient distance to completely dry themoistened paper before rolling it up after being embossed.

R is a tie-girt connecting the main side frames of the machine with thestands for supporting the outer roll for supporting the apron O, whichroll is not shown inv the drawings, but may be of any ordinaryconstruction.

S is a shaft mounted in bearings in the main frames of the machine, andhas mounted thereon the roll of paper, S",which is to be embossed. Thepaper to be embossed is moist- IOO ened, and the end of the Web isplaced upon the apron I and passed beneath the die-roll D, and is thussubjected to a heavy preasure between the die-roll D and the apron Ialong a narrow line above the apex of the rounded rib c of the bedgirtH, the rubber outer surface of the apron I yielding to permit theprojecting portions of the design on the die-roll to embed the paper insaid rubber Without so stretching the apron, either longitudinally ortransversely, as to wrinkle or Vtear the paper. The embossed paperpasses from the apron I upon the heated metallic apron O, to be conveyedto a sufficient distance away to be thoroughly dried, when it is rolledup or otherwise disposed of to put it in suitable condition for themarket.

Other materials-such as paper or paperpulp combined with cloth orwood-may be embossed successfully upon this machine.

l/Vhat I claim as new, and desire to secure by Letters Patent of theUnited States, is-

1. In a machine for embossing paper,wood, or other material, thecombination of a revolving die-roll, a fixed bed-girt beneath saiddierolland havingarounded upwardlyprojecting rib extendinglongitudinally thereof and opposed to and parallel with the undersurface of said roll, and a flexible and yielding feed-apron vsupportedby said rounded rib, and. mechanism, substantially as described, formoving the periphery of said dieroll and the upper surface of said apronin unison, as set forth.

2. In a machine for embossing paper,wood,' or other material, thecombination of a revolving die-roll, a fixed bed-'girt beneath saiddieroll and having a rounded upwardly-projecting rib extendinglongitudinally thereof and opposed to and parallelvvith the undersurface of said roll, an endless feed-apron supported by said roundedrib, and mechanism, substantially as described, for moving the peripheryof said die^rol1 and the upper surface of said apron in unison, as setforth.

In testimony Whereofl have signed my name to this specification, in thepresence of two subscribing Witnesses, on this 22d day of June, A. D.1887.
